INSPECTION PROCEDURE
CAUTION:
Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.
Tech Tips
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
Note
If any of the DTCs U0110-159, U0110-656, and U0110-657 was set due to incomplete engagement of the connectors, and if the system returns to normal when the power switch is turned on (IG) after clearing the DTCs, DTC P324E-788 will be set. Proceed to troubleshooting without considering DTC P324E-788.
Tech Tips
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
Turn the power switch on (IG) and wait for 2 minutes or more.
PROCEDURE

Check MG1 for an interphase short using a milliohmmeter.
Using a milliohmmeter, measure the resistance according to the value(s) in the table below.
Tech Tips
If the MG1 temperature is high, the resistance will vary greatly from the specification. Therefore, measure the resistance at least 8 hours after the vehicle is stopped.
Standard Resistance | ||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|

Tech Tips
To correct the variation of the measured resistance due to temperature, use the following formula to calculate the resistance at 20°C (68° F).
R20 = Rt / {1 + 0.00393 X (T - 20)}
The calculation is based on the following:
R20: Resistance at 20°C (68° F) (mΩ)
Rt: Measured resistance (mΩ)
T: Temperature when the resistance is measured (° C)
Using a megohmmeter set to 500 V, measure the resistance according to the value(s) in the table below.
Note
Be sure to set the megohmmeter to 500 V when performing this test. Using a setting higher than 500 V can result in damage to the component being inspected.
